Scientists coax shy microorganisms to stand out in a crowd Posted: 02 Feb 2012 01:48 PM PST Scientists have advanced a method that allowed them to single out a marine microorganism and map its genome even though the organism made up less than 10 percent of a water sample teeming with many millions of individuals from dozens of identifiable groups of microbes. |
Google Earth ocean terrain receives major update Posted: 02 Feb 2012 01:48 PM PST Internet information giant Google updated ocean data in its Google Earth application this week, reflecting new bathymetry. |
New way to study ground fractures Posted: 02 Feb 2012 12:16 PM PST Geophysics researchers have created a new way to study fractures by producing elastic waves, or vibrations, through using high-intensity light focused directly on the fracture itself. |
Yellow Biotechnology: Using plants to silence insect genes in a high-throughput manner Posted: 02 Feb 2012 12:12 PM PST Scientists are now using a procedure which brings forward ecological research on insects: They study gene functions in moth larvae by manipulating genes using the RNA interference technology (RNAi). RNAi is induced by feeding larvae with plants that have been treated with viral vectors. This method called "plant virus based dsRNA producing system" increases sample throughput compared to the use of genetically transformed plants. |
Castaway lizards provide insight into elusive evolutionary process, founder effects Posted: 02 Feb 2012 12:11 PM PST A biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed. He found that the lizards' genetic and morphological traits were determined by both natural selection and a phenomenon called founder effects, which occur when species colonize new territory. |
Prolific plant hunters provide insight in strategy for collecting undiscovered plant species Posted: 01 Feb 2012 03:14 PM PST Today's alarmingly high rate of plant extinction necessitates an increased understanding of the world's biodiversity. An estimated 15 to 30 percent of the world's flowering plants have yet to be discovered, making efficiency an integral function of future botanical research. |
